Human experimentation. United States and Canada decide to slow down human reproduction research.

Abstract

Louise Brown, the world's first "test-tube" baby, celebrated her 15th birthday on July 25. Three months later, the whole field of in vitro fertilization and human embryo research was thrown into a tizzy. Public reaction in response to embryo-cloning experiments in the United States brought a halt to the research project, and the release of a set of recommendations by an expert panel in Canada called for limits on embryo tests and experimentation. Each event contains the same underlying message--it's not nice to meddle with Mother Nature.
